I see the world with my eyes, they reflect what's going on in my head. 

A tangle of thoughts, memories, experiences and learned knowledge.

This shapes my perception of the world around me.
Do I see the world as a good place or a bad one.
My behavior, my decisions and feelings are the result.

When I become aware of it, I can influence it. 

I can see how I want to see and influence it in a positive way.
